[sumo-user] Getting a warning for a collision

[rohan g. <roh...@ya...>]

I am trying to get a warning for a collision taking place at a junction in SUMO. However, even after setting the junction as 'traffic_light_unregulated', and the --collision.check-junctions set as true and the --collision.action warn set as well, I do not get a collision warning in SUMO. 
I request you to please help me with the required changes to get a warning for such collisions.
The attachments include the example files.
